Does java come with a debugger?
I've never used the language but i'm sure it does?
Where in your code does it stop executing?

[PHP]r7.GetEmployees().New(Desc.getText().toString());[/PHP]

Your not sending enough information to the constructor. Your giving it one string when its asking for 4 different variables.

[PHP]New(java.lang.String,java.lang.String,java.sql.Date,java.lang.String)[/PHP]

So either add in the missing variables or make another version of New (not a great name btw) that takes in just one string.
